Modeling the Behavior of Pre-Stressed Concrete Railroad Ties

2015 Joint Rail Conference, 2015
Early failure of pre-stressed concrete railroad ties in the field is a costly occurrence with modern ties. A key predictor of the performance of a pre-stressed concrete cross tie is the transfer length. Assuring that the transfer length is less than the position of the rail seat is necessary to establish the full pre-stressing force at the load point ...

Failure mechanisms of reinforced and pre-stressed concrete structures

Revue Européenne de Génie Civil, 2006
ABSTRACT This paper deals with specific aspects of nonlinear computation of reinforced and pre-stressed concrete structures. The constitutive equations dedicated to concrete cracking, concrete-steel bond rupture and corroded steel yielding are described.

Reliability of Pre-stressed Elliptical Paraboloidal Concrete Shells

IABSE Reports, 2018
<p>This paper describes a numerical and experimental analysis model used to estimate (a) transient bi-directional strains due to the concrete creep and shrinkage, (b) the resulting time-dependent bi- directional stress redistribution, as well as (c) bi-directional displacement variations in the structural shell elements and (d) bi-directional pre-

Investigation of the Pre-stress Loss in the Dynamical Behaviour of Concrete Beams

2008
The work addresses the effect of pre-stress on the dynamic behaviour of concrete structures. At this purpose peculiar attention is paid to the eigenfrequencies and the relevant modal shapes of beams that share the same geometrical and mechanical parameters but are acted upon by different levels of pre-stress force.
